The correct answer is Velocity of the car is constantly changing.

Key Points

• We all know that the car is speeding up as we bring our foot down on the accelerator.
• The rate of change in the velocity of a particle with respect to time is called its acceleration.
• If the velocity of the particle varies at a constant rate, this rate is called constant acceleration.
• As we use meters and seconds as our basic units, we calculate acceleration in meters per second per second.
• It will be abbreviated as m/s².
• For example, if the velocity of a particle moving in a straight line varies uniformly (at a constant rate of change) from 2 m/s to 5 m/s over a second, then its constant acceleration is 3 m/s².

The correct answer is real.

Key Points

• Irrational numbers are real numbers that cannot be represented as simple fractions.
• It cannot be expressed in the form of a ratio, such as p/q, where p and q are integers, q(0).
• It's a contradiction of rational numbers. Irrational numbers are generally expressed in the form of R\Q, where the backslash symbol denotes 'set minus'.
• It can also be represented as R-Q, which shows the difference between the set of actual numbers and the set of rational numbers. Calculations based on these numbers are a little difficult. For example, √5, √11, √21, etc, are irrational.
• If these numbers are used in arithmetic operations, we need to test the values under root first. These values may also be recurring occasionally.
• An irrational number is a real number that cannot be represented as a ratio of integers, e.g. √2, it is an irrational number.

Given:

Telephone bill for 3 minutes 20 seconds = Rs. 25.50

Calculations:

3 minutes = 3 × 60 = 180 seconds

⇒ 3 minutes 20 seconds = 180 + 20 = 200 seconds

similarly,

⇒ 5 minutes = 5 × 60 = 300 seconds

⇒ 5 minutes 30 seconds = 300 + 30 = 330 seconds

200 seconds → Rs. 25.50

1 second → Rs. 25.50/200

⇒ 330 seconds → Rs. 330 × 25.50/200

⇒ 330 seconds → Rs. 42.075 ≈ Rs. 42.1

Concept used:

If given a : b : : c : x

then x is called the fourth proportion.

It can be calculated as,

a/b = c/x

⇒ x = bc/a

Calculations:

12 : 18 : : 20 : x

then,

x = (18 × 20)/12

⇒ x = 30

∴ Fourth proportion = 30

Additional information:

First proportion - If x : a : : a : b, then x is called first proportion.

Mid Proportion - If a : x : : x : b, then x is called mid proportion.

Third Proportion - If a : b : : b : x, then x is called third proportion.

Calculations:

$\frac{{3.24 \times 4}}{{0.2}} = ?$

$\Rightarrow \frac{{12.96}}{{0.2}} = ?$

$\Rightarrow \frac{{12.96}}{{0.2}} \times \frac{{100}}{{100}} = ?$

$\Rightarrow \frac{{1296}}{{20}} = ?$

$\Rightarrow \frac{{324}}{5} = ?$

$\therefore ;? = \frac{{324}}{5}$

The Correct Answer is Dissolved Oxygen.

• Dissolved oxygen (DO) is an indicator of the quantity of free oxygen molecules in water.
• The concentration of DO is an important indicator of the health of the aquatic environment, as oxygen is essential for almost all forms of life.
• Oxygen is essential for respiration and chemical reactions. Dissolved oxygen in water comes from two primary sources: atmospheric and photosynthesis.
• The concentration of DO is influenced by a variety of factors, including water temperature (cold water retains more oxygen than warm water), salinity (freshwater holds more oxygen than saltwater), and atmospheric pressure (the amount of DO consumed in water decreases as the altitude increases).
• The parameter is capable of calculating dissolved oxygen in water within a range of 0 – 500% or 0 – 50 mg/l.

The Correct Answer is Xenon.

Key Points

• Xenon(Xe) is a component of zero-valence elements called noble or inert gases.
• It is inert to most normal chemical reactions (e.g. combustion) since the outer valence shell contains eight electrons.
• This results in a stable, minimum energy configuration in which the outer electrons are tightly bound.
• The first published report confirming xenon anaesthesia was published in 1946 by the American medical researcher John H. Lawrence.
• Xenon has been undiscovered for a very long time, although it is present in traces in the atmosphere. It is still a subject of interest due to its reactivity with many elements in a specialised and regulated environment, hence the name "Stranger Gas."

Important Points

• Neon is a chemical element with the Ne symbol and atomic number 10. It is a noble gas. Neon is a colourless, odourless, inert monatomic gas under normal conditions, with an air density of around two-thirds.
• Krypton is a chemical element with the Kr symbol and atomic number 36. It is a colourless, odourless, tasteless noble gas that exists in trace quantities in the atmosphere and is mostly used in fluorescent lamps with other rare gases.
• Argon is a chemical element with a symbol of Ar and an atomic number 18. It is a periodic table in group 18 and is a noble gas. Argon is the third most abundant gas in the Earth's atmosphere, at 0.934 per cent (9340 ppmv).

We have to find rank of Rashmi in the class.

Statement 1-: There are 25 students in the class. 

This statement is only saying about total students in the class, but this alone statement is not enough to find Rasmi's rank in the class.

Statement 2-: There are 8 students who have scored les than Rashmi.

This statement is saying that 8 students have scored less than Rashmi, means if we know total number of students then we can find Rashmi's rank, but this alone statement is not enough to find Rasmi's rank in the class.

So by combining statement 1 and 2 we can find Rashmi's rank.

Total students - students who scored less than Rashmi 

= 25 - 8

= 17

Hence, Both the statements together are needed.

Given:

Buying cheat = 15%

Selling cheat = 15%

Calculation:

Let 1 gm = 1 rs, total quantity is 100 gm

At the time of buying, he gains 15% by wrong weight

⇒ 100 × (100 + 15)/100

⇒ 115 gm = S.P

He sells at 15% by wrong weight 

It means he sells 15% less fruit.

⇒ 100 × (100 - 15)/100

⇒ 85 gm = C.P

Profit% = (115 - 85)× 100/85

⇒ 3000/85

⇒ 35.29%

∴ His total gain, in percentage, is 35.29%.

Given:

Radius of cylinder = 2 cm

Height of cylinder = 2 m = 200 cm

Formula used:

Volume of cylinder (V) = π × r² × h

where,

Given:

sinx = 4/5 

Formula Used:

sin²x + cos²x = 1 

secx = 1/cosx

tanx = sinx/cosx 

Calculation:

We know that, sin2x + cos2x = 1

⇒ cos²x = 1 - (4/5)²      (∵ sinx = 4/5)

⇒ cosx = √9/25

⇒ cosx = 3/5 

Now,

secx + tanx = (1/cosx + sinx/cosx)

⇒ (1 + sinx)/cosx

⇒ (1 + 4/5)/3/5

⇒ 9/3

⇒ 3

∴ secx + tanx = 3

Concept Used: 

Tournament performance is said to be bad for a team when it loses more matches than winning i.e when Loss/Win ratio is greatest.

Calculation:

Loss/Win Ratio in 1st match = 3/5

Loss/Win Ratio in 2nd match = 4/4

Loss/Win Ratio in 3rd match = 2/5

Loss/Win Ratio in 4th match = 3/6

Loss/Win Ratio in 5th match = 2/4

Loss/Win Ratio in 6th match = 3/3

Loss/Win Ratio in 7th match = 4/2

Clearly,the Loss/Profit ratio in 7th match is greatest. 

∴ Hence seventh tournament was the worst for the team

Calculation:

⇒ Total matches won by team = 5 + 4 + 5 + 6 + 4 + 3 + 2

So total matches won by the team are 29

Concept Used:

success ratio = matches won/total matches played

Calculation:

⇒ For 1st tournament success ratio = 5/8 = 0.625

⇒ For 2nd = 4/8 = 0.5

⇒ For 3rd = 5/7 = 0.71

⇒ For 4th = 6/9 = 0.66

⇒ For 5th = 4/6 = 0.66

⇒ For 6th = 3/6 = 0.5

⇒ For 7th = 2/6 = 0.33

So we can see that in 3rd tournament success ratio is best for team

Calculation: 

Total matches played = 50 

Total matches won by team = 29

Percent of the match won by the team overall = match won/total matches played × 100

⇒ 29/50 × 100 

⇒ 58%

We have to check the options by given the equation:- (Using Bodmas):

 Option.1) 9 + 9 > 9 = 9

 ⇒ 9 ÷ 9 + 9 < 9

 ⇒1 + 9 < 9

 ⇒10 < 9 ( does not follow)

Option.2) 9 < 7 + 7 = 6

 ⇒ 9 - 7 ÷ 7 < 6

 ⇒ 9 - 1 < 6

⇒ 8 < 6 (does not follow)

Option.3) 7 # 7 > 77 + 7 = 7 # 7 > 1

⇒ 7 × 7 + 77 ÷ 7 < 7 × 7 + 1

⇒ 49 + 7 < 49 +1

⇒ 56 < 50 ( does not follow )

Option.4) 7 > 7 < 7 + 7 = 14

⇒ 7 + 7 - 7 ÷ 7 < 14

⇒ 14 -1< 14

= 13 < 14

Hence, option 4 is the correct answer.

The correct answer is The elected members of both Houses of the Parliament.

Key Points

• The Vice-President shall be chosen indirectly by an electoral college consisting of members (elected as well as nominated) of both Houses of Parliament, in accordance with the system of proportional representation by means of a single transferable vote, and the vote shall be by secret ballot.
• The election of the Vice-President is somewhat different from the election of the President, since the members of the state legislature are not part of the electoral college, although the nominated members of both houses are part of the electoral college for the vice-presidential election.
• The nomination of a candidate for election to the office of Vice-President must be signed by at least 20 electors as nominees and 20 electors as nominees.
• The Vice-President may resign by submitting his resignation to the President. The resignation shall become effective from the date on which it is approved.

Given:

Mrs. Vijaya takes a total of 9 hours 50 minutes in walking a distance and running back to the same place where she started. She could walk both ways in 12 hrs 20 minutes.

Formula Used:

speed = distance/time

Calculation:

⇒ Total time taken to cover the whole distance is 9 hours 50 minute when she walk while going and run while returning

also, she would cover the whole distance in 12 hours 20 minutes, if she only walked

Let the distance be x, speed for running be 'r' and speed for walking be 'w' 

⇒ x/w + x/r = (9 + 50/60) hours 

⇒ x/w + x/r = 9 + (5/6)       ----(1)

But it will take 12 hours 20 minutes if he walks 

⇒ 2x/w = 12 + 20/60  ( 2x is total distance for both ways)

⇒ x/w = 6 + (1/6)      ----(2)

Now put this value x/w = 6 + (1/6) in equation (1) we will get x/r = 3 hours 40 minutes or 3 + (2/3) hours

So total time taken by running only = 2x/r = 2 × [3 + (2/3)]

⇒ 2x/r = 7 hours 20 minutes         

Alternate Method Let W be walking time and R be running time

W + R = 9 hr 50 mins

W + W = 12 hr 20 mins ⇒ 2W = 12 hr 20 mins ⇒ W = 6 hr 10 mins

So, R = 9 hr 50 mins - 6 hr 10 mins = 3 hr 40 mins

So both ways = 2R = 2 × 3 hr 40 mins = 7hr 20 mins

Given:

Two buses start from a house at an interval of 5 minutes and move with a speed of 10 km/hr in the same direction. 

Formula Used:

distance = speed × time

Calculation:

⇒ So the distance between them will be the distance covered by the bus in 5 minutes or 5/60 hour

So distance covered by bus in 5 minutes = 5/60 × 10 = 5/6 km

Now woman coming from the opposite direction will cover the distance between bus in time = Distance between buses/(speed of bus + speed of women)

⇒ 3/60 = (5/6)/(10 + speed of women)                               (time = 3 minutes or 3/60 hours) 

⇒ speed of woman = 20/3 kmph

All these originated in North India → no, Kathakali, Bharathanatyam are the dance forms of South India, while Kathak and Madubani are dance forms of North India.

 All are practiced by female artists only → no, all can be practiced by male and female artists.

All are South Indian dance forms → no, Kathakali, Bharathanatyam are the dance forms of South India, while Kathak and Madubani are dance forms of North India.

Hence ,There is no similarity at all is the correct answer.

Given:

The cash difference between the selling price of an article at a profit of 4% and 8% is Rs. 3.

Formula Used:

selling price = cost price + profit

profit% = (profit/cost price × 100)

Calculation:

Let the cost price be 100x 

So selling price will be when profit % is 4% = 100x + 4% of 100x = 104x

⇒ Similarly selling price when profit % is 8% = 100x + 8% of 100x = 108x 

⇒ Difference between both selling price = 108x - 104x = 3 

⇒ 4x = 3 or x = 3/4

Now the ratio for both selling price = 104x/108x = 26/27      

∴ required ratio = 26 ∶ 27

Given:

Ms. Revathi borrowed Rs. 600 at 6% simple interest

Formula Used:

simple interest = p × r × t/100

(where p is money borrowed, r is rate of interest and t is total time)

Calculation:

Now she has to return money after 4 years 

⇒ So total amount she will pay will be money borrowed + interest for 4 years

Interest for four years = p × r × t / 100 

So, total interest for four years will be = 600 × 6 × 4/100 = 144 

So, total amount given to clear debt = 600 + 144 = Rs. 744

• Researchers also observed that the extent of the moon's very minor wobble, when it orbits Saturn, can only be accounted for if the outer ice layer is not frozen solid within it, meaning that the global ocean must be present.
• The discovery contains a fine spray of water vapour, ice particles and basic organic molecules that Cassini has detected coming from cracks near the south pole of the moon, being supplied by this large pool of liquid water.
• The research is discussed in a paper released online this week in the Icarus magazine.
• Cassini scientists have studied more than seven years of Enceladus images taken by a spacecraft that has been orbitary Saturn since mid-2004.

Important Points

• Tethys is the fifth largest moon in Saturn.
• Mimas, also known as Saturn I, is a moon of Saturn discovered by William Herschel in 1789. It's named after Mimas, Gaia's son in Greek mythology.
• Rhea is the second-largest moon of Saturn and the ninth-largest moon throughout the Solar System.

The least possible Venn diagram for the given statements is as follows:

Conclusion:

I. Some ducks are cows. --> False (It is possible but not definite)

II. Some cows are ducks. --> False (It is possible but not definite)

Thus, the correct answer is "Neither I nor II follows".

Given:

Mr. Arun borrowed Rs. 6500 at 4% per annum compound interest. 

Formula Used:

C.I. = P( 1 + R/100)² – P

Calculation:

C.I. = 6500(1 + 4/100)² - 6500

⇒ 6500{(104/100)² - 1)} = 6500 {(104² – 100²)/100²}

⇒ 6500(104 + 100)(104 – 100 )/10000

⇒ 65(204)(4)/100 = (260 × 204)/100

⇒ 530.4

∴ The correct answer is Rs. 530.4.

Shortcut Trick

The effective rate for 2 yrs at 4%

⇒ 4 + 4 + (4 × 4)/100

⇒ 8.16%

C.I = 6500 × 8.16%

C.I = 530.4

The correct answer is Decomposers.

Key Points

• Decomposers are the largest population of the food chain.
• These are organisms that feed on dead and decaying matter and break down complex compounds into simpler ones.
• This involves bacteria, fungi, and a variety of other microorganisms.
• Decomposers are an integral component of the food chain. They break down the carbon-free organic matter and other nutrients that are useful for their growth as well as for the development of plants.

Important Points 

• The producers are at the first trophic stage of the food chain.
• It acts as a nutritional supply for consumers or a higher trophic level.
• Producers are responsible for the processing of organic compounds made from ambient or marine carbon dioxide.
• The primary consumer is an organism that feeds primary producers.
• Primary consumers are usually herbivores that feed on autotrophic plants that produce their own food by photosynthesis.
• Secondary consumers are species that absorb energy from primary consumers.

The logic is :

G = 7

EXCEL = 5 + 24 + 3 + 5 + 12 = 49

Similarly,

ACCEPT = 1+ 3 + 3 + 5 + 16 + 20 = 48

Thus, the correct answer is "48".

The correct answer is Mammals.

Key Points

• Elephants, Bears and Rhinos are examples of Mammals.
• Mammals are a group of vertebrate animals of the class Mammalia, characterised by the presence of mammary glands which in females, provide milk for feeding their young, brain region, fur or hair, and three middle ear bones.
• The most common orders are rats, bats and eulipotyphs (hedgehogs, moles, shrews, and others).
• The next three are the Primates (ape-like humans, chimpanzees, among others), the Artiodactyla (cetaceans and even-toed ungulates) and the Carnivora (cats, dogs, seals, and others).
• The basic body shape is quadrupled, and most animals use their four extremities for terrestrial locomotion; but in others, the extremities are modified for life at sea, in the clouds, in forests, underwater, or on two legs. Mammals range in size from 30–40 mm (1.2–1.6 in) bumblebee bat to 30 m (98 ft) blue whale-possibly the largest mammal known to have existed.
• Maximum lifespan ranges from two years in the shrew to 211 years in the bowhead whale.

The correct answer is French Guiana.

Key Points

• INSAT-2E is an Indian geostationary communications and weather satellite operated by the Indian National Satellite System.
• INSAT-2E was launched by Arianespace, using the Ariane 42P carrier rocket from ELA-2 to the Guiana Space Centre**.**
• It is located in a geostationary orbit at a range of 83° East from where it is used to provide communications services to Asia and Australia.
• It also contains two meteorological instruments, the Very High-Resolution Radiometer, and a CCD camera capable of returning photographs with a resolution of one kilometre.
• The payload communications on INSAT-2E consists of 17 G/H bands (IEEE C band) transponders.
• At launch, the satellite had a mass of 2.550 kilogrammes (5.620 lb), with an estimated service life of 12 years.
